Stretch-resistant coils for intracranial aneurysms: one step forward or two steps back?

CT showed that our needle was too deep and the glue had reached the hypothalamus. The patient spent a week in the intensive care unit, and though he completely recovered, it still gives me goose bumps to think about it. There is no consensus about the most comfortable temperature. The way we perceive temperature has a lot to do with the humidity accompanying it. For example, if the humidity is 0%, 24°C will feel like 21°C, while with a 100% humidity, 24°C will feel like 27°C. The most comfortable humidity levels are between 40% and 50% (levels also said to prevent upper respiratory tract infections). In places with extreme outside temperature variations, it is recommended that inside temperatures be kept at 21°–23°C (69°–73°F). 9 In the United States, the Occupational Safety and Health Administration recommends a range of 20.5°–24.5°C (68°–76°F) and humidity between 20% and 60% at workplaces. 10 Another anecdote: Upon arriving in Panama City, my colleague and friend, Dr Ilka Guerrero asked me if I had brought a sweater because the city was about the coldest place on earth. After entering my hotel, I understood what she meant. Air conditioning thermostats were kept at 16°C (62°F). Those of us who grew up elsewhere in warmer latitudes never cease to be amazed by how cold buildings are kept in the United States (they are even colder in the United Kingdom where regulations dictate temperature at the workplace be " reasonable " —that is, 16°C (61°F)! 11 Cold inside buildings is a luxury, and it has been documented that the most expensive stores (Hermes, 20°C) are kept colder than the least expensive ones (Old Navy, 27°C). 12 Apparently colder spaces encourage us to buy more and also save electricity. We radiol-ogists must work in cold environments because computers and monitors (not to forget the view boxes of the past) generate a lot of heat and reading rooms can only be kept comfortable by lowering the thermostat. Work productivity is better at stable and slightly lower temperatures 13 but colder temperatures are uncomfortable and the New York Public Library allows their workers to accrue compensatory time when its temperature drops below 20°C (68°F). It is a common belief that heavier individuals are more sensitive to heat (and conversely will feel cold to the touch), while skinny ones are sensitive to cold (but will be hot to the touch).
